TECHNICAL FIELD

The invention refers that when firing does not deviate from the sightline in vertical direction, that shall be applied, either as a means ofself-defense, or as a hand-held fire weapon for sports, military andhunting firing,

PRIOR ART

When firing with pistols—representatives of the well-known systems ofhand-held smallarms, it is found shifting of the barrel “upwards”,because of the following:

When firing with pistols from the well-known systems, there are reactionforces created (the so-called recoil), directed “backwards” along thebore line of the weapon, as these forces create a torque round theweapon support point and as a result the front end of the barrel jumps“upwards”. The reason causing the motion is the disposition of the boreline above the place of weapon retaining, i. e. above the support point.

This effect is obtained when firing with pistols, one-charge andmany-charge non-automatic hand-held weapons and is the reason for theirbasic disadvantage—the low rate of fire accuracy. (1)/“Reference Book ofSmallarms”, A. B. Zhuk/

At automatic self-loading weapons, the deviation from the sight line,when firing, is accelerated due to the motion of bolt parts, as thechange in location of weight centres of elements of the weapon at highspeeds creates inertia forces and moments additionally that aggravateaccuracy.

In order to overcome the action of inertia forces during fire at thistype of weapons, extra measures are taken as: corrections in sightingdevices; mounting muzzle compensators, balances and retarders of firerate; introducing disconnectors and buffers.

A disadvantage of automatic pistols is the complicated design that leadsto difficulties in their handling. (2)/“Reference Book of Smallarms”, A.B. Zhuk/

There are pistols known where the barrel axis is guided to the weaponsupport point (the firer's palm) and it is avoided bouncing the pistol“upwards”. (3)/U.S. Pat. No. 4 268 987 and pistols “Tourbean” 1883 and“Protector” 1882/ “Reference Book of Smallarms”, A. B. Zhuk//

Disadvantages of these pistols are: the complicated design that hampersusage, reloading, reduces reliability, requires special ammunition; badergonomics and low effectiveness of firing.

It is known a sports pistol of T-shaped location of grip and barrel,consisting of a casing provided with a grip, a barrel, a trigger locatedabove the barrel within the zone between the muzzle rear end and thegrip, a bolt, a striker, a fire spring and a magazine. (4)/History ofTula Military Plant/

Disadvantages of this pistol are the risen overalls and its complexdesign that make its handling difficult

The famous sports pistol can not be regarded as an analogue of thepresent invention, as it is provided with special devices ensuringimproved aiming fire that complicates its design and makes itimportable.

It is known a pistol consisting of a casing, a barrel, a trigger, astriker, a fire spring and a magazine, the casing and the barrel beinglocated in a heat-insulating grip and forming a T-shape connection bymeans of a dismountable multi-element clamp provided with a triggermounted on it and situated above the bore line of the barrel within thezone between the front and the rear muzzle ends connected with thefeeding mechanism consisting of a feeding lever, a feeding pawl beingfixed on its opposite end by means of a trigger mechanism consisting ofa transfer bar geared into a striker lever provided with a cog so thatthe casing is provided with an inner bore of rectangular cross-sectionand set inside it a magazine provided with a cartridge nests set in arow and saw-like cogs set along the height of the side neighbour wallsjust before the rear wall of the magazine and fixing grooves locatedalong the axes direction of cartridge nests so that the number ofsaw-like cogs situated on each of the neighbour walls of the magazinecorresponds to the number of cartridge nests, the casing being closedfrom above and a striker, a fire-spring, an upper stop and a lower stopbeing fastened to its rear wall and a profile opening. (5))/FR-A-550415/

The disadvantages of this pistol are the complicated design whichincludes a multi-element clamp connecting the barrel with casing upperend, the indirect connection between the trigger and the feedingmechanism by means of the trigger mechanism the result being a difficultuse and reloading, a decreased reliability and a low fire efficiency.The ergonomics and the heat insulation of the grip are not reliableenough witch determine the insufficient fire accuracy.

The goal of this invention is to be created a portable pistol forself-protection of T-shaped disposition of the barrel and the casing,reduced weight and overalls of the weapon, high accuracy of fire andconvenient handling.

HANDLING THE INVENTION

When using the Pistol, subject of the present invention, of designdescribed in Example 1, cartridges are arranged in a metallic magazinewith cartridge nests formed inside and the magazine is moved in astep-like down-up way behind the barrel through the action of thetrigger pull./FIG. 1, & FIG. 3/

Handling is carried out in the following way:

After filling the magazine 15 with cartridges in the cartridge nests 15,it is proceeded with the pistol loading. To this end, the filledmagazine 14 is inserted into the grip 3 through the lower opening of theinner bore 13 from the bottom to the top till the moment the first fromthe saw-like cogs 16, located along the right neighbour wall, contactsthe short arm 24 of the V-shape upper stop 20. At the same time thelower stop 21 situated on the opposite wall locks it in this position sothat the top most cartridge is set under the bore line. Through theprofile opening 22 in the rear wall of the casing 1, the feeding pawl 12is facing the saw-like cogs 16 of the magazine 14.

Pulling the trigger 5 brings simultaneously to rotating the striker 18“backwards” round its axis set under the bore line, through the actionof the transfer bar 8 that draws out the striker lever 9 upwards, thecog 10 pushes the long arm 25 of the upper stop 20 “backwards” and takesout the short arm 24 from gearing with the magazine 14.

From the other end the feeding pawl 12 starts gearing with the fixinggrooves 17 of the magazine 14 and drawing it upwards sliding along thevertical edge of the profile opening 22. When the feeding pawl 12contacts with the upper edge of the profile opening 22, it changes themotion direction into, “forward” locking the magazine 14 to the casing1. Besides, the first cartridge has been fed against the barrel 2. Atthe same time the transfer bar 7 releases the striker lever 9 andthrough the action of the fire spring 19, the striker 18 hits thecartridge primer and takes a shot.

Through the action of the spring 66 depressing its upper end, the upperstop 20 enters over the subsequent saw-like cog 16 of the magazine 14along with the striker 18, as its short arm 24 gears with the saw-likecogs 16 of the magazine 14 and its long arm 25 remains behind the cog 10of the striker lever 9 and the lower stop 21 has already missed onesaw-like cog 16 and is geared under the next one. Releasing the trigger5, which is under-spring, brings to going out of the feeding pawl 12from the fixing groove 17 of the magazine 14 and reversing in homeposition. The transfer bar 7 moves downward till the cog 10 gears againwith the striker lever 9. So, the pistol is ready for the next shot.After firing the cartridges from the magazine 14 or upon othernecessity, the lower end of the lower stop 21 is pushed forward, so thatits lower under-spring end is below the level of the grip 3 and themagazine 14 goes out through the action of its own weight. Afterwardsthe pistol is loaded with a second filled up magazine 14 or the cases ofthe magazine already taken out are replaced with cartridges.

When using the pistol, subject of the present invention, of designdescribed in Example 2, cartridges are arranged in a metallic magazinewith cartridge nests formed inside in a row and the magazine is moved ina step-like up-down way behind the barrel through the action of thefeeding spring folded in advance./FIG. 1, FIG. 4, FIG. 5 & FIG. 6/

Handling is carried out in the following way:

The magazine 14 is set in the inner bore 13 of the casing 1. To load thepistol, the grip 39 is withdrawn backwards, as the cap 31 is opened upto 90°, so that the upper stop 36, the lower stop 37, the latch 38 ofT-shape, the striker 18 and the fire spring 19 are moved along with thecap 31 backwards and upwards, as the excess to the magazine 14 isreleased being in lower extreme position depressed by the feeding spring44. The arm 32 of the cap 31 pushes downward the elevating frame 34 tillthe elevating cog 35 seizes the lock pin 30 situated at the lowest pointof the vertical slot 43. Cartridges are set into cartridge nests 15.After loading the magazine 14, the cap 31 is closed. The elevating drawsthe magazine 14 upwards so that the feeding spring 44 is depressed, sowhen reaching an upper position, the elevating cog 35 releases the lockpin 30. At the same time the lower stop 37 has entered the zone ofgearing with the lowest saw-like cogl6 of the magazine 14. Through theaction of the feeding spring 44 the lower stop moves downward along itselongated opening. The upper stop 36 gears with the lowest saw-like cog16 of the magazine 14 from its opposite side. The first cartridge hasbeen introduced into the barrel 2 and the pistol is ready for fire.

Pulling the trigger 5 brings simultaneously to rotating the striker 18“backwards” round its axis set under the bore line, through the actionof the transfer bar 8 that draws out the striker lever 9 upwards, thecog 10 pushes the short arm 24 of the lower stop 37 “backwards” andtakes out the long arm 25 from gearing with the magazine 14, so that itslong arm 25 skips the top of the saw-like cog 16 and goes out of gearingwith it and through the action of the spring 67, the lower stop 37raises along its elongated opening clamping into the inter-cogs area Atthe same time the cradle 27 geared into the trigger 5 turns round andwithdraws the fixing pawl 29 along the fixing slot 41 into thesubsequent fixing groove 17 of the magazine 14.

Afterwards the transfer bar 8 releases the striker lever 9 and throughthe action of the fire spring 19, the striker 18 hits the cartridgeprimer fires a shot

Releasing the trigger 5 brings to pushing the fixing pawl 29 from thecurrent fixing groove 17 of the magazine 14. The so-released magazine14, through the action of the feeding spring 44, goes downward and thelower stop 37 meets the next saw-like cog 16 of the magazine 14 with itslong arm 25, descending along its elongated opening, depressing thespring 67, so that the next cartridge has been introduced into thebarrel 2. After firing all the cartridges from the magazine, the cap 31is unclamped by drawing the grip 39 backwards. Meanwhile, the ejector 33has remained before the rims of cases moving downwards and when openingthe cap 31, seizes and draws them from cartridge nests 15 of themagazine 14, so that the magazine 14 is ready for refilling.

The Pistol, subject of the present invention, of design described inExample 3, is a self-loading pistol and functions according to thesystem-long stroke of barrel forward at an immovable bolt./FIG. 7, FIG.8/

Its handling is carried out in the following way:

After filling the magazine 47 with cartridges, it is proceeded withpistol loading. To this end the filled magazine 47 is thrust into thegrip 3 through the lower opening of the inner bore 13 down-up till themoment when the closing cover 49 fixes to the casing 1 by means of theS-shaped latch 59, so that the upper cartridge is clamped to the outersurface of the barrel 2 within the thickened zone. After that the grip39 of the cover 54 is withdrawn backwards till stoppage. By thekinematics chain, the cover 54, the cradle 55, the guiding pawl 65 andthe cross groove 53, the barrel 2 is pushed forward depressing thespiral recoil spring 50. The upper cartridge is pushed upwards by thepushing spring 48 of the magazine 47 till its rim enters the ejector 57.When releasing the grip 39 of the cover 54, through the action of thespiral recoil spring 50, the barrel 2 reverses backwards and thrustsonto the fed cartridge. The cover 54 also returns back and closes fromabove the inner bore 13 of the casing operating as a case outlet. Thepistol is ready for fire, as the first cartridge has been introducedinto the barrel 2.

Pulling the trigger 5 cocks the striker 18 by means of the transfer bar8, afterwards it releases the striker lever 9 and through the action ofthe fire spring 19, the striker 18 hits the cartridge primer and fires.

When firing, the bullet sets forth into the barrel and the frictionforces affect it. The barrel shifts forward, as moves simultaneouslylinear and rotary motion round its axis and as a result of sliding thecogs 61 along the guiding grooves 52, slant longitudinally towards thebore line. Shifting forward, the barrel 2 goes out of the case scope,opens the cover 54 and folds the spiral recoil spring 50. When reachingfront extreme position, the end of the cradle 55, moving backward, hitsthe upper end of the deflector 56, so that the pawl 58 knocks out thecase from the ejector 57 and it flies upwards through the case outlet.At the same time the unoccupied place has been taken from the nextcartridge, so that the barrel 2, returned back by the spiral recoilspring 50, is thrust onto it. After releasing the trigger 5, the pistolis ready for the next firing. Reloading is carried out, as the S-shapedlatch 59 is pressed backward, so that the emptied magazine 14 is takenout and replaced with a newly-filled one.
